ATTORNEY Patented July 15, 1952 OFFICE ALLOVER BEDCANOPY 'ro.ADMINIST'ER OXYGEN Thaddeus A. Taylor, Luiki n, Tex. V Application July13, 1951, Serial No. 236,506 10 Claims. (01. 12s 191) The presentinvention relates to improvements in bed canopies, oxygen tents and thelike and more particularly to all-over-bed canopies or tents toadminister oxygen to a sick patient, and particularly adapted for usewith refrigeration and oxygen supply means of standard makes.

Usually heretoioreoxygen tents, canopies and the like have not beensumciently sealed because there is provision only to tuck the bottomedge under the mattress and there is a great loss of oxygen through themattress and around the edge of the canopy. Also when the tent or canopyis removed from under the mattress for nursing care there is stillfurther loss in oxygen concentration in the tent.

The present invention greatly reduces oxygen loss by providing incombination with the upper part of the tent a sealed base section ofgas-tight material for either enclosing the entire mattress or forresting on top of the mattress, whereby all mattress undertucking iseliminated and all nursing care and treatment of the patient in theinterior of the up er part of the tent may be performed through slidefastener sealed openings at the head, foot and sides of the tent withoutmaterial loss of oxygen concentration. Accordingly an object of theinvention is to provide a gas-tight canopy or the like, which may bemounted to completel cover the top of the mattress as a unit or whichmay be arranged to completely enclose the mattress, whereby any passageof oxygen and air through the mattress material fails to reduce oxygenconcentration and only a small liter of flow is needed.

Another object is to provide a novel bed canopy for d nis ering oxy en,which is forrred of two separable upper and lower sections, the lowersection or bottom section being of generally durablepermanentnon-transparent material and formed to enclose the bottom andsides of a mattress, theupper or top section being of trans-' parentmaterial detachable from the relatively more permanent non-transparentbottom section without disturbing the mattress or a patient recliningthereon, whereby new top sections can be re laced when torn or worn outand whereby the bottom section which is less likely to be damaged maycontinue to be used with each new top section.

A further obiect is to provide sl de fasteners completely around thehead and foot of the upper edge and lower edge of the respective bottomand top sections of the canopy, whereby the sections may be separatedand connected at the head or foot of the canopywith a minimum of timeand effect to facilitate nursing care and various forms of treatment.

Still a further object isto provide slidejastener sealed openings in theupper section of the canopyat the side, foot and end of the bed fornursing care and treatment of the patient during the process ofadministering the oxygen without much loss in concentration of oxygen inthe tent. I

Yet another object is to provide slide-fastener means in the wall of theupper section for a sealing connection around the intake and outletconduits of an ice cooling unit or a refrigeration unit foruse with orwithout the oxygen supply.

Still another object is to provide as an article of manufactureaseparable two part oxygen tent of simple, durable and inexpensivegas-tight material, wherein either part of the tent may be soldseparately for replacement purposes if desired.

With these and other objects in view which will become apparent as theinvention is fully understood, the same resides in the novelty of,construction, combination and arrangement of elements hereinafterdescribed in detail and distinctly claimed in the appended claims.

The description should be read in conjunction with the accompanyingdrawings wherein:

Referring in detail to the drawings and first with particular referenceto Figures 1 and 2, there is shown a bed A, a mattress B, a canopysupporting stand C at the head of the bed and a canopy support D at thefoot of the bed. As illustrated the canopy I9 is completely enclosingthe mattress B and comprises a bottom nontransparent section II, whichcovers the. bottom and most of the'sides of. the mattress; The' upperrim of the section II is edged with spaced apart lower sections I2 andI3 respectively of slide fasteners I4 and I5, which cooperatewithsimilarly spaced sections I6 and Il fastened-to the lower edge of theupper canopy section I8 of said respective slide fasteners I4 and I5.Thus slidefast;

ener section I2 of the canopy bottom section and slide fastener sectionI6 of the upper canopy sec tion when joined together encompass-or-encircle the mattress at the head of the bed from each .side, while.thefastener lower section I3 and .the

upper fastener section I'l'encircle the mattress atthe foot of the bedfromeach sideto therelugs-of each slide fastener. are positioned inaligned .spacedapart relation on each end of a .m'ultii-ply snapfastener closure for anopening 2 I' as shown in Figure8.

This multi-ply closure isgas-tight and comprises .a looped overstripwith the overlapping outer. flap'2'3isecuredito the upper sectionI8 of the tent by stitches '2'4; .inFigure '6. The outer flap carriesthe femaleparts of two or more snap fasteners and25, while the inner legoriiap of the'loopficarrie's. a plurality oflmale parts 2i, 28.18,.30,3I and. 32', .whi'chsnaps connect with thecooperating femaleparts-ZI';28, 29', 30", 3I' and 32 of a doubled overffiap. 33 stitched to thelower tent se'ctioii'l I. As shown in Figures 6' and 8-the.flap33=fitsbetween fla s-22 and 23 so-t at male snap. fasten relements 21through 32 on flap 2'2. snapflt with the female fastener elements onfiaoe33'. .After these. are. snapped together then the outer flap 23folds over and'fe ale snap elements 25 and'ZSI engage with maleelementsZB' and 26' on he exterior .side of flan 33.- Disconnection ofthese. snap fasteners make the opening ZI available for uses, such asstomach. drainage, chestabscess .drainaqeand the like.

.Most all patients takingv oxygen need blood transfusions orglucose. anditis important to pro ide closure means "for this purpose in the wallsof the canopy so there will be very little loss :of oxvgenconcentration. As illustrated. in Figure lithere are numerous sealedslide fastener openings for these and similar pur oses. For

example, at the .foot of the canopy II! is a; slide fastener. adapted.to provide access to the feet oi the patient when the tent is setup.The "foot of the tent. orcanopy Ill 15. held above the feet of thepatient by elongated straps 35 andSS', respectively, spaced aparton-each s de of the slidefas- .tener 34.. These straps are. stitchedtothe exterior of the canopy- IO andinclude a snap fastener element oneach of their respective ends soithat when the. straps are looped aroundan upstand- U-shaped support 31 having right angled =feet 3'8 .an'dl39,whichfit under the mattress .B,

thefoot of the canopy is held elevated above the mattress B to enhancethe patients comfort.

.The head of the canopy is held in elevated ioperating position by meansof tabs 4I' having treatment to the patient and the slide fastener maybe closed around the arm of the doctor or nurse giving ,the treatment oraround the arm of the patient for transfusions and the like, therebyavoiding any appreciable loss of oxygen dining'the treatment. Inaddition to closure 43 and substantially perpendicular to the same are-slideastener closures 44 and 45 for giving medication, water andnourishment. These closures 'like43 may be closed around the arm of thenurse or. person giving the treatment or the like.

Similar slide fastener openings may be on the opposite side, if desired,and just below the dome 40 on this side -are two spaced apart -multiplezipperclosures 46 each for'connecticnwith an icecooled unit or with anair conditioning unit-48 by encircling the inlet and outlet pipes 49 and49a; respectively, see Figuresl and 4. An oxygen tank 50 with asupplyline 5| may alsoilend into the canopy at this connection.

The basesection II of the canopy It] may be mounted on top of themattress if desired'by using the anchoring tabs 52 secured in eachcorner and on each side to the exterior of the base action material bystitches '53. The free end of each tab hangs down' over th sidesof thmattress B and pin fasteners 54 or thelike'securethe-tabs to themattress material. 7 7

Operation anduse- The operation and-use or the presentinvention isbelieved to be apparent from the foregoing detailed description. Forexample, to completely enclose the mattress B, the base section I I isapplied to the bottom of the mattress and sides with the upper canopysection I8 detached, next the dome, 40- of the canopyand its tabs II areattached to the hooks on-the support arms 42 and the main slide fasteneranchors of' the respective top and bottom canopy sections are lockedtogether as well known in the slide fastener art. The slide elements I4and I5 are adiacent their respective pairs of anchorelements on theirside of the canopy and may now'be slid at wilaround their respectivepaths of travel to enclose the head of the mattress and the foot of themattress. Prior to closing the main slide fasteners I 4 and i5, thecanopy foot support 37 is put in position at the foot of the mattressand straps 35 and '36 are looped over the top bar of the support andsnapped into holding position."

This now causes the canopy to be held to proper shape and the patientmay be placed on the, mattress before the main slide fasteners areclosed on one side of the mattress.

The same general operation takesplace when using the base section II ontop-of the mattress B and the same is secured to the mattress by tabs 52and pin fasteners 54.

It'often is desirable to fold back the upper section I8 of the canopyand open the main slide fasteners around the head and foot of the canopypermitting the rear side to stay fastened. To facilitate folding back ofthe upper section I8, there are provided handle loops 68 adapted to begripped by the nurse to raise and fold over the side of the canopy Ill.

The air conditioner unit and oxygen supply are readily attached byinserting the connecting pipes 19 within the double slide fasteneropenings as shown in Figure 4 on the sideof the dome portion 40 and itis of course understoodthat such connections may be provided at the rearof the dome portion instead of the side, if desired, A safety valve 6|is shown in Figures 1 and l; and another 'valve, not shown, if desiredmay be mounted in the wall of the upper section l8. Also to provide asafety vent for excess pressures in the tent, the slide fasteners 14 andI 5 may be left slightly open at the side, thereby permitting escape ofexcessive air and oxygen and also C02 7 which is exhaled by the patient.A graduated air meter may-be connected to the oxygen gausefso; that acertain amount of air may be given with the oxygen.

Thus there is provided an all-over-bed oxygen canopy that can beoperated on top of the matf tress or with the mattress completelyhousedinside the same. Also there is provided a canopy with a topcompletely removable from the base section of the canopy by separatinghead and foot slide fasteners, one around the head and one around thefoot of the canopy, said top section having further slide fasteneropenings for nursing care and treatment of the patient without much lossof oxygen in the canopy, and double slide fastener openings for airtight connection with conduit connections from an air conditioning unitand/or an oxygen supply tube.

While the foregoing specification describes and the drawings illustratethe specific details ofthis invention, it is to be understood that thesame'is not limited by these details and is therefore susceptible tochanges and modifications within base section, and-tabs with pinfasteners secured to the exterior corners and sides of "said sealedbasesection, saidtabs hanging adjacent the sidesj of a mattress on whichsaid base sec-' tion is resting,whereby said pin fasteners ma be securedto the sides of the mattress.
